It is at once immense, humbling, crumbling, and full of grandeur. It baffles that bricks of normal size were used to make a building of such immensity. In Power Station A, the level of art deco detailing is amazing. The valves and dials in the control rooms speak of a different age, when the belief in progress was not naive or foolish. The rubble strewn across the site speaks of the wider neglect of the public domain of the last 25 years.

We ran out of superlatives.

The regeneration plans for the site are coming on apace too. For once, a building with a stunning past has a pretty rosy future too.
